A 4-wire power supply connection must be used when the appliance is installed in a
location where grounding through the neutral conductor is prohibited. Grounding
through the neutral is prohibited for (1) new branch-circuit installations, (2) mobile
homes, (3) recreational vehicles, and (4) areas where local codes prohibit grounding
through the neutral conductors.
If using a power supply cord:
Use a UL listed power supply cord kit marked for use with clothes dryers. The kit should
contain:
■
A UL listed 30-amp power supply cord, rated 120/240 volt minimum. The cord should be
type SRD or SRDT and be at least 4 ft (1.22 m) long. The wires that connect to the dryer
must end in ring terminals or spade terminals with upturned ends.
■
A UL listed strain relief.
If your outlet looks like this:
4-wire receptacle (14-30R)
Then choose a 4-wire power supply cord with ring or spade terminals and UL listed strain
relief. The 4-wire power supply cord, at least 4 ft (1.22 m) long, must have four 10-gauge
copper wires and match a 4-wire receptacle of NEMA Type 14-30R. The ground wire (ground
conductor) may be either green or bare. The neutral conductor must be identified by a white
cover.
If your outlet looks like this:
3-wire receptacle (10-30R)
Then choose a 3-wire power supply cord with ring or spade terminals and UL listed strain
relief. The 3-wire power supply cord, at least 4 ft (1.22 m) long, must have three 10-gauge
copper wires and match a 3-wire receptacle of NEMA Type 10-30R.
If connecting by direct wire:
Power supply cable must match power supply (4-wire or 3-wire) and be:
■
Flexible armored cable or nonmetallic sheathed copper cable (with ground wire),
protected with flexible metallic conduit. All current-carrying wires must be insulated.
■
10-gauge solid copper wire (do not use aluminum).
■
At least 5 ft (1.52 m) long.
GROUNDING INSTRUCTIONS
SAVE THESE INSTRUCTIONS
■
For a grounded, cord-connected dryer:
This dryer must be grounded. In the event of malfunction or
breakdown, grounding will reduce the risk of electric shock
by providing a path of least resistance for electric current.
This dryer uses a cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged
into an appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
■
For a permanently connected dryer:
This dryer must be connected to a grounded metal,
permanent wiring system, or an equipment-grounding
conductor must be run with the circuit conductors and
connected to the equipment-grounding terminal or lead on
the dryer.
WARNING:
Improper connection of the equipment-
grounding conductor can result in a risk of electric shock.
Check with a qualified electrician or service representative
or personnel if you are in doubt as to whether the dryer is
properly grounded. Do not modify the plug on the power
supply cord: if it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
